Application Driven Testing of Drools with Fitnesse – part 3


Overview

In this post we will migrate our tests to Fitnesse using the Wili Pages

Problem Domain

So far we have created a simple rule and a JUnit test to test it.  But what if the client wants to see what we have?  They’re not going to want to read JUnit tests written in Java.  They want the tests and data to be presented in a format that they can understand.

Furthermore, what if the client wants to change the test data?  Our test so far has two Person objects, one aged 18 and one aged 21.  What if the client wants to add more Person objects?  They’re not going to want to go editing Java code – even if it is a JUnit test; and they’re certainly not going to want to fire up Eclipse.  They want a simple, user friendly interface.

Enter Fitnesse…

Approach

First let’s create the Wiki page that defines our test.  This will give us a good idea of the Fixtures we need to put in place to bolt everything together. Once we have done this, we will go on to create the Fixtures and run complete Application tests.

Creating the Web Page

Startup Fitnesse by running the Run Configuration we used in Part 1.

This will launch Fitnesse on port 8080.

Open your browser to http://localhost:8080/

This will display the following page:

001-fitnessedefaultpage

click the edit button and change the content to the following:

!1 Skills421 Drools Fitnesse Example

| Test Suites |
| [[Person Tests][FitNesse.PersonTests]] | Simple Rules Tests using Person Facts |

click save and your page will look like the following

002-testmenu

click on the red [?] on the page and this will create a new default page and open it in edit mode.

click save

click Add -> Test Page

Page Name: SimplePersonTest

click save

Your PersonTests page will now look like this

003-persontests

Click on the Simple Person Test link

click edit

replace the text with the following:

!contents -R2 -g -p -f -h

!2 Test Data Setup
!3 Person

|Jane     | Doe    |22 |1.9     |70      |

Click save and your page will look like this

004-persondata

click on Test and you will see the following error:
